Dr. Peter Bodenheimer and his colleague at the University of California, Santa Cruz, Dr. Douglas Lin will use theoretical techniques to study the progression through the process of star formation to the formation of planets. The theoretical models are constrained by the properties of the planetary system as well as by the rich observational information now available regarding young stellar objects. The origin and evolution of the solar nebula and the formation of the planets provides a challenging problem for the theorist. Theories must explain extensive compilations of observational data, ranging from meteoritic abundance anomalies to the properties of outflows from young stars. Recently there has been a rapid accumulation of infrared and ultraviolet data from T Tauri stars, which has led to the strengthening of the hypothesis that accretion disks are present around many of these objects. These disks may be protoplanetary disks. A wide variety of physical processes is involved and must be incorporated into theoretical studies of star and planet formation. Drs. Bodenheimer and Lin concentrate on the formation and evolution of the solar nebula itself. Significant progress is being made with the aid of enhanced interdisciplinary contact and improved computer facilities.

彼得·博登海默（Peter Bodenheimer）博士和他在加利福尼亚大学圣克鲁斯分校的同事道格拉斯·林（Douglas Lin）博士将利用理论技术通过恒星形成的过程来研究行星形成的过程。 理论模型受到行星系统的特性以及现在可用的有关年轻恒星对象的丰富观察信息的限制。 太阳星云的起源和演变和行星的形成为理论家提供了一个具有挑战性的问题。 理论必须解释观察数据的广泛汇编，从陨石丰度异常到年轻恒星流出的特性。 最近，来自T Tauri恒星的红外和紫外线数据迅速积累，这导致了人们在许多这些物体周围存在积聚磁盘存在的假设。 这些磁盘可能是原行星磁盘。 涉及各种各样的物理过程，必须将其纳入恒星和行星形成的理论研究中。 博士。 Bodenheimer和Lin集中在太阳星云本身的形成和演化上。 借助增强的跨学科接触和改善的计算机设施，正在取得重大进展。
